I will present the ALPHA collaboration's latest calculation of the Lambda parameter of QCD. Our method relies on experimental inputs of low energy quantities like pseudo-scalar decay constants only. The scale dependence of a coupling in a finite volume renormalization scheme is computed non-perturbatively in lattice QCD over many orders of magnitude in the energy scale. At high energies perturbation theory is safely applied to obtain the Lambda parameter in any scheme.
